The authors have noticed that the therapies mentioned in the “Allocation” boxes in figure 1 of the above manuscript were incorrect. The left-hand box should read: “4203 allocated budesonide/formoterol maintenance and reliever therapy 160/4.5 μg one inhalation twice daily + as needed (1×2)”. The right-hand box should read: “4221 allocated budesonide/formoterol maintenance and reliever therapy 160/4.5 μg two inhalations twice daily + as needed (2×2)”. A corrected version of figure 1 from the above manuscript is presented below. The authors apologise for this error.
